← Logic & PuzzlesIf a self-regulating HVAC system in a museum uses temporal logic to maintain stable humidity, which consequence follows when a specification requires humidity to be *always* within bounds?
A)Humidity fluctuates temporarily and corrects
B)Humidity is occasionally outside of range
C)Humidity drifts gradually over time
D)Humidity remains continuously within range✓
💡 Explanation
The 'always' operator in temporal logic mandates that a condition must be true at all points in time; therefore, if the HVAC specification requires humidity to be *always* within bounds, humidity must remain continuously within the defined range, rather than exhibiting fluctuations or drifts.
